Final answer:
When two patients require assistance, use the call light to alert a co-worker to help the other resident while you continue to assist your current patient safely.
Step-by-step explanation:
If you are assisting a patient and another resident begins calling out for help, the appropriate action would be to use the call light to notify a co-worker to check on the resident calling out. This allows you to maintain safety for the patient you are currently assisting without leaving them unattended, which could result in a fall or injury. It also ensures that the other resident gets the attention they need in a timely manner. Safety should always be prioritized in healthcare settings.
